I agree with Mr Fixit on this one also. In fact, VW used to sell an optional, centrifugal-only distributor refered to as the "009" which was very popular with the modifiers and dune buggy crowd. I used one on a 75 SuperBeetle from which I had removed the unreliable fuel injection system. That car used a "double diaphragm" model which didn't have any centrifugal advance at all. John Muir, who wrote the book "How To Keep Your VW Alive For The Complete Idiot," hated the vacuum advance units and recommended that any VW owner switch just out of general principle. I installed one and it worked like a champ. The MSD unit on my present car is centrifugal advance only and it also works well.
